Graduated needle knife

Abstract

The invention discloses a graduated needle knife, which includes a needle knife body, a gourd-shaped knife handle, a needle body and a graduated plate. The gourd-shaped knife handle is composed of anupper handle cover and a lower handle cover, the inner end faces of the upper handle cover and the lower handle cover are bonded to each other, T-shaped grooves are formed in the middle parts of the upper handle cover and the lower handle cover correspondingly, and a sliding cavity and a threaded cavity are formed in the upper ends of the inner parts of the upper handle cover and the lower handlecover correspondingly. According to the graduated needle knife, the gourd-shaped knife handle is formed by bonding the upper handle cover and the lower handle cover, the structure is simple, manufacturing is easy, the gourd-shaped knife handle is placed in the T-shaped grooves for positioning and fixing through a needle seat, in addition, a pin penetrates through a circular hole to play an auxiliary fixation role on the needle seat, control of the handle to the needle body is convenient, through the depth by positioning a bolt downwards, the graduated plate is extruded to achieve positioning and fixing of graduation of the graduated plate, thus the entering depth can be checked from the graduation number, and through two ways of graduation observing while working or graduation depth setting and then working, depth control and accurate positioning of the needle knife can be overall realized well.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a graduated needle knife. Background technique [0002] Acupuncture knife is a new type of medical device that integrates acupuncture needles and scalpels. Acupuncture knife therapy is a minimally invasive technique of traditional Chinese medicine developed on the basis of nine needles in ancient my country and combined with modern medical surgical scalpels. Several generations of clinical practice and exploration have gradually formed a theoretical system of acupotomy medicine. Acupuncture medicine believes that soft tissue injury and disease can cause the body's dynamic balance imbalance, and gradually appear pathological changes such as adhesion, contracture, scar, blockage, etc., and the chronic soft tissue injury of the human body is not just a single point of disease, but is based on the anatomical system of the bowstring mechanics of the human body. Form a three-di...

Problems solved by technology

[0003] In traditional clinical operations, according to the anatomical structure and image data, although more accurate positioning and operation depth measurement can be performed, since the traditional needle knife does not have a scale mark, in actual operation, the depth and accuracy of needle knife release are often determined by different surgeons. Grasp, stay at the experience level, there are often limitations, blindness, and even insufficient risk control for deep tissue and intra-articular needle-knife operations
